您好，我最近在ROCK5B-PLUS适配IMX290出现问题，由于我能力问题，无法进一步确定原因，希望您能帮忙看看。
需求设计：
- 根据ROCK5B-PLUS的MIPI CSI CAM硬件接口定义，定制了IMX290模组，大部分都与ROCK5B-PLUS CSI引脚定义一致，只是将FPC线的28，29，30分别定义为IMX290的vddd、vdddo、vdda，和ROCK5B-PLUS的MIPI CSI CAM的28、29、30定义不太一致。
- 参照Radxa Camera 4K的设备树实现了IMX290的Overlay设备树，并在内核源码中启用了编译了IMX290驱动。
- 如图所示连接IMX290与ROCK5B-PLUS的CAM0口；
问题描述：
在系统中启用IMX290设备树，并加载imx290.ko；打印以下错误：
疑问：
- 我的IMX290设备树实现有什么问题吗？
- ROCK5B-PLUS的28、29、30引脚可以配置为（vddd、vdddo、vdda）对应的电压范围吗？
